Design filter with aggressive space mapping algorithm

The coarse and fine models of a PCB multiplayer filter were established with ADS and HFSS software,respectively.The design of models was optimized by the aggressive space mapping algorithm.The filter was fabricated and tested.Results show that the PCB multilayer filter has a central frequency of 1.85 GHz,a bandwidth of 300 MHz and an insertion loss of less than 2.3 dB.The feasibility of the aggressive space mapping algorithm is proved.
